[OpenSIPS-Users] Truncated Branch in Via

We are using opensips 1.11.5 as a stateless proxy and seeing a truncated Branch in Via for my REGISTER message. After some code digging, the MAX length is calculated using the following formula and seems like its truncating the branch after 55 characters. This is causing the REGISTER to fail in our case. Is there a config level solution to this ?

#define MAX_BRANCH_PARAM_LEN  (MCOOKIE_LEN+8 /*!<int2hex*/ + 1 /*sep*/ + \
                                MD5_LEN + 1 /*!<sep*/ + 8 /*int2hex*/ + \
                                1 /*extra space, needed by t_calc_branch*/)

truncated from opensips -->     Via: SIP/2.0/UDP XX.XX.XX.XX:5060;branch=z9hG4bK0fddbbc9-1487-4755-a0b3-0c319155b8c3_0efbfc5e_11160
Via from EndPoint    -->                Via: SIP/2.0/UDP XX.XX.XX.XX:5060;branch=z9hG4bK0fddbbc9-1487-4755-a0b3-0c319155b8c3_0efbfc5e_1116078308924346_MTAuMTIuMy4xMQ
